Buy yourself time to make the best business decision

There’s a silent risk inside your business. Right now.

Most SME organisations are still running critical Microsoft systems that no longer receive security updates, or are about to lose support entirely.

This may not seem urgent, because these systems don’t simply stop working. But they do become immediately vulnerable.

It’s happening. The 13th October 2026 is a hard deadline.

Windows Server 2012 reaches its final Extended Security Update Expiry.

After this date:

  • No patching
  • No support
  • No fallback

At the same time, multiple core Microsoft systems reach end of support.

The countdown is on until your systems are vulnerable.

This is not simply an IT Issue. It’s a very real business risk.

Security Risk

Unsupported systems expose unpatched vulnerabilities

Compliance Risk

Failure to meet regulatory frameworks (GDPR, FCA, NIS2)

Financial Risk

Breaches and downtime create significant cost and disruption

The biggest risk happens during transition

Most organisations are planning migration. But migration timelines don’t necessarily match security risk timelines. That leaves a gap:

Legacy systems still live

Security risk increasing daily

No structured protection
